Answer:

  • proportional
  • $15 per hour

Step-by-step explanation:

We aren't told what the 1, 2, 3, 4 represent. If it is number of children, then the question makes no sense. We have to assume it is probably hours.

  dollars/hours = 15/1 = 30/2 = 45/3 = 60/4 = $15/h

The rate is a constant, so amount is proportional to hours.

Drag and drop the constant of proportionality into the box to match the table. If the table is not proportional, drag and drop "
Nikitich [7]

The table is proportional and the constant of proportionality is 1.5

Step-by-step explanation:

Proportional relationships are relationships between two variables

where their ratios are equivalent

  • One variable is always a constant value times the other
  • The relation between the two variables represented graphically by a line passes through the origin point

The table:

→ x  :  0  :  2  :  4  :  6

→ y  :  0  :  3  :  6  :  9

To prove that y ∝ x find the ratio between each value of y with corresponding value of x

∵ \frac{3}{2}=1.5

∵ \frac{6}{4}=1.5

∵ \frac{9}{6}=1.5

∴ \frac{y}{x}=k

∴ k = 1.5

∵ The origin point is in the table

∴ y ∝ x

∴ The table is proportional

The table is proportional and the constant of proportionality is 1.5

Plz help last one ty!!!!!!!
azamat

My apologies on answering late...

Same situation as the previous problem, but this time, all you need to do is state the degree of the angle instead of just providing the angle itself.


ΔABC ≅ ΔDEF

Now, we can see that ∠C ≅ ∠F. Using this information, we can find ∠C on the first triangle ( which is 75° ).

Since ∠C ≅ ∠F,

m∠F is 75°.


Hope I caught your question in time!

Have a good one! If you need anymore help, let me know.
